+* Samsung S3C2410 and compatible NAND flash controller
+
+Required properties:
+- compatible : The possible values are:
+	"samsung,s3c2410-nand"
+	"samsung,s3c2412-nand"
+	"samsung,s3c2440-nand"
+- reg : register's location and length.
+- #address-cells, #size-cells : see nand.txt
+- clocks : phandle to the nand controller clock
+- clock-names : must contain "nand"
+
+Optional child nodes:
+Child nodes representing the available nand chips.
+
+Optional child properties:
+- nand-ecc-mode : see nand.txt
+- nand-on-flash-bbt : see nand.txt
+
+Each child device node may optionally contain a 'partitions' sub-node,
+which further contains sub-nodes describing the flash partition mapping.
+See partition.txt for more detail.
+
+Example:
+
+nand-controller@...00000 {
+	compatible = "samsung,s3c2440-nand";
+	reg = <0x4e000000 0x40>;
+
+	#address-cells = <1>;
+        #size-cells = <0>;
+
+	clocks = <&clocks HCLK_NAND>;
+	clock-names = "nand";
+
+	nand {
+		nand-ecc-mode = "soft";
+		nand-on-flash-bbt;
+
+		partitions {
+			compatible = "fixed-partitions";
+			#address-cells = <1>;
+			#size-cells = <1>;
+
+			partition@0 {
+				label = "u-boot";
+				reg = <0 0x040000>;
+			};
+
+			partition@...00 {
+				label = "kernel";
+				reg = <0x040000 0x500000>;
+			};
+		};
+	};
+};
